Castle of Black Iron
Castle of Black Iron - Chapter 1646: Couldn't Go Back

Castle of Black Iron was Zhang Tie's most powerful trump card and reliance. As long as he could use Castle of Black Iron, he would tide over difficulties one after another. However, when Zhang Tie wanted to use Castle of Black Iron in this strange place, he found that he couldn't. Therefore, he became a bit flurried at a stroke.

"Heller, heller, could you hear me?" Zhang Tie hurriedly called Heller. Based on his experience, even if Castle of Black Iron didn't work, he could still contact Heller. As long as the marvelous arch door of Castle of Black Iron was in his mind sea, he would be able to contact Heller.

"I'm here, Castle Lord. Congratulations, Castle Lord, you've survived the combat..."

Heller's voice was as calm as before. Despite being a bit emotional, Heller's words finally made Zhang Tie a bit calm.

"What happened? Why couldn't I use items in Castle of Black Iron? The space-teleportation function of Castle of Black Iron becomes ineffective!"

"Castle Lord, do you remember your experience in the tower of time? In the tower of time, as long as it starts, Castle Lord would not be able to use Castle of Black Iron!"

"Aah, what? You mean I'm in a tower of time?"

"You're not in a tower of time. However, the use of Castle of Black Iron is restricted to the irresistible strength in the twisted time-space structure of this world." Heller said calmly.

"How could be that?"

"Castle Lord, do you remember how you felt when you entered this world?"

Zhang Tie recalled it carefully as he replied, "I might be sucked in. The moment my virtual image of king rock entered the entrance of this weird space, it had been sucked in an irresistible manner together with me!"

"It is the bizarre strength of the twisted time-space structure of this world. Castle Lord, if you take this world as a huge balloon and Castle of Black Iron a smaller one, what would happen if the smaller one was put in the huge balloon or being connected to the larger one by a pipe?"

"If the smaller balloon was put in the bigger one, it would sustain great stress. If the smaller one was connected with the bigger one, it would shrink and shriveled in the end!"

"What space-teleportation items such as Castle of Black Iron is to this space is similar to what the smaller balloon is to the bigger one. Therefore, Castle of Black Iron is not available."

"Is the space-teleportation as same as the others?"

"Yes!"

"But why?"

"Precisely, this is not a complete world; nor a parallel universe. Given the strength of its time-space structure, it's more like an artificial world. However, it is destroyed to a certain degree and becomes volatile!"

After hearing Heller's words, Zhang Tie's heart raced as he almost exclaimed, "An artificial world? Impossible?"

"Castle Lord, have you forgotten that Castle of Black Iron would be as same as this world as time flies..."

"You mean, I could not use Castle of Black Iron forever in this world?"

"Not absolutely. Strength is always presented periodically like how grasses and woods wither and revive, the sun rises and falls, the moons wax and wane. The strength of the time-space structure in this world should be periodical too. On some junctures, Castle of Black Iron is still available!"

Heller finally revealed a "good news" which could make Zhang Tie a bit relaxed. However, closely after that, Zhang Tie recalled something as his face suddenly changed. When he had not recovered his strength, Zhang Tie was thinking about recovering his strength as soon as possible; however, Heller's words reminded Zhang Tie of a more serious problem. Unlike Castle of Black Iron, he couldn't access this world whenever he liked. Additionally, as this world was isolated from the former world where he was, how could Zhang Tie return to the former world?

"Could I go back?" Zhang Tie swallowed his saliva and asked Heller hardly after being shocked for a short while.

Heller was in silence for a while too, which brought Zhang Tie an inauspicious premonition.

After quite a while, Heller's voice reappeared in Zhang Tie's mind sea.

"Castle Lord, I couldn't answer you. Because I couldn't foresee the future; nor help you from outside. I could only tell you that the strength of this time-space structure is shrinking. It's similar to a swirl in the abyss under the ocean, Castle Lord must have a deep feeling about it. As long as you're sucked into such a swirl, you could barely come out unless your strength is greater than the suction or the swirl disappears..."

Zhang Tie was dumbfounded. After that, he hurriedly asked Heller, "Above Yinhai, I felt a wave caused by broken space-teleportation equipment beside Heavenly Hunyuan. It was like a powder keg being detonated by a sparkle, which instantly created a hole and entrance in the surroundings. If I return to the place where I appear at the beach and break some space-teleportation equipment over there, could I find the entrance and the route back?"

"No, the reason is what I've mentioned. Because the strength of this time-space structure is shrinking, even if Castle Lord could find the entrance where you come to this world, you couldn't go back along the same route. You should know that the entrance to space appears and disappears at any time. Even though the entrance doesn't disappear, it's just unidirectional..."

Zhang Tie was petrified. Although Heller left some hope to him in his words, Zhang Tie realized that he could barely return to Taixia Country and the familiar world.

When he remembered his parents, his wives and kids and those familiar and intimate faces that he might not see any longer, Zhang Tie dropped tears at once...

After a while, the door was pushed open as a surprised voice sounded, "Aah, you're awake..."
